This involves set periods of eating and fasting. Popular methods include- the 16/8 Method, where one fasts for 16 hours and eats during an 8-hour window and the 5:2 Diet, where one eats normally for five days of the week and restricts calories on the other two days.
Alternate between days of normal eating and fasting days where calorie intake is very low (about 500 calories).
Eat small amounts of raw fruits and vegetables during the day and have one large meal in the evening, within a 4-hour eating window.
Fast for a full 24 hours once or twice a week, typically from dinner to dinner or lunch to lunch.
Fast for 23 hours and eat one large meal in a 1-hour window each day.
Fasting for periods longer than 24 hours, such as 48 or 72 hours. This should be done with caution and ideally under medical supervision.
Note: It is important to choose a method that fits your lifestyle. Consult a healthcare provider before starting any fasting regimen, especially for extended fasts.
